Below is the code for JAVA, the code for C# is almost identical.

Case 1: Binary relation “=”

$$2=3$$

import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("2=3");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: 2=3 = 0.0

Case 2: Binary relation “<“

$$2<3$$

import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("2<3");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: 2<3 = 1.0

Case 3: Boolean operator “OR”

$$(2=3)\vee(2<3)$$

import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("(2=3) | (2<3)");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: (2=3) | (2<3) = 1.0

Case 4: Boolean operator “AND”

$$(2=3)\wedge(2<3)$$

import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("(2=3) & (2<3)");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: (2=3) & (2<3) = 0.0
